.1. L. MORRIS DISPENSING APPARATUS Filed March 1s, 1924 7 Sheets-Sheet 7INVENTOR HHHII Y 0,. n 11: n M m- ,RW Z Z /ff wwf H l uw W 7 7 Y 9 w M W`29 adapted to cooperate with adapted to contain the material to bepackaged. This hopper has an outlet 8 controlled by a cut-off meansillustrated in detail in Figure 3. This cut-off means may compriseshutter sections 9 and 10 adapted to closely engage along the line 11 onsubstantially the median line of the outlet 8, as

clearly shown in Figure 2. The shutter section 9 is provided with a pairof racks 12 and the shutter section with a similar pair of racks 13.OneA of the racks of each pair is in engagement with a gear 14, theengagement being with substantially diametrically opposite portions ofeach of the gears whereby rotation of the gears will cause the .sectionsto move uniformly and in opposite directions. These sections areYmounted to slide in suitable guides 15 suitably, positioned withrespect to the outlet 8. With this construction, it will be apparentthat with the shutter sections in the position illustrated in Figure 3the flow of material from the hopper 7 will be prevented, while with thesections in open position, a free flow will be permitted, the rate offlow depending' upon the material being. handled and upon the extent ofopening of the sections.

The sections of the cut-off means are adapted to be manually moved toopen position by a bell crank lever 16 pivotally mounted on a pin 17carried by the frame 2. One end of the bell crank lever is shaped toprovide an operating handle, while the opposite end is pivotallyconnected to a link 18 which is, in turn, pivotally connected to theshutter section 9.v Adjustably mounted on the link 18 is a movable stop2O having an indicating finger 21 adapted to cooperate with suitablegraduations 22 on the link. The movable stop may be held in any desiredposition by a set screw 23. The graduations 22 are so arranged that theyindicate the extent of opening of the shutter sections 9 and 10, itbeing apparent that the graduations thereon may be of any arbitrarycharacter. Positioned so asto engage the movable stop is a fixed stop24. Carried by the pin17 is a spring 25 arranged to normally turn thebell crank lever 16 in a clockwise direction to move the shutter section9 to the right, as viewed vin Figures 1, 2 and 3, and the shuttersection 10 to the left, thereby cut-ting 0E the flow through the outlet.Normally, this closing movement of the shutter sections is prevented bya detent 26 adjustably mounted in a slot 27 formed in the projection 28on the shutter section 10. This detentmay also be provided with anindicating linger graduations 30 on a projection 28, these graduationspreferably being similar to the graduations 22 and arranged in reverserelationship.

Mounted to cooperate with the detent 26 is a trigger 31 preferablyhaving a pivotal mounting 32 in a casting 33 projecting outwardly fromone. side of the hopper 7. On its under side the trigger 31 carries aroller 34 adapted to cooperate with the detent 26. By referring moreparticularly to Figure 7 of the drawings, it will be seenthat thisdetent has its outer side gradually curved7 while its inner side formsan abrupt shoulder. In this ligure, the roller 34 is shown in theposition it occupies with relationk to vthe detent when the shuttersections are closed. Tn the drawings, the movable stop 2O and the detent26 are shown in such position that their respective indicating lingerscooperate with the graduation 3. This corresponds, with the graduationsshown, to approximately a half open position of the shutter sections. Inoperation, with the movable stop and the detent arranged as described,the operator will grasp the handlel portion of the bell crank lever 16and move it in a counter-clockwise direction. This will serve to openthe shutter sections to an extent restricted by the engagement of themovable stop 20 with the fixed stop 24. At this time, the curved surfaceof the detent 26 will have-passed under the roller 34 and permitted 'theroller to drop ahead of the detent, as indicated in dotted lines inFigure 7. Gravity acting upon the trigger 31 will maintain the roller 34in this position, and thus prevent closing of the shutter sectionsuntilthe detent is released. It will be understood that with each changeof setting of the movable stop 20, the detent 26 will be correspondinglyadjusted whereby proper cooperation at all settings is insured betweenthe detent and the trigger. In operation, the scales 6 are fro placed onthe platform 5 that a receptacle R on one of the platforms will directlyunderlie the outlet 8. Upon the accumulation of a predetermined weightof material in this receptacle, the detent is adapted to beautomatically released. This may be accomplished by securing to one ofthe platforms an arm 35 having an adjustable extension 36 carrying aclamp 37. This clamp is adapted to cooperate with a vertically extendingrod 38, the upper end of which shaped to engage the trigger-loop 39 of abalance or scale beam 40. This beam is delicately mounted to move aboutbearings 41 within the limits of the keeper 42, as well understood inthe art. On one end of the beam is a cage 43 within which are spacedparallel tracks 44 upon which is adapted to travel a ball 45. In orderto protect the tracks 44 from any accumulation of foreign material. andat the same time to permit observation of the ball 45, the cage may beprovided with trani;- parent means 46.

At the commencement of the filling operation of a receptacle, the beam40 will be so balanced that it will occupy the position il- I :tornicarrying the `arm 35.

The

simultaneous CII a transverse shaft 63 having adjacent each end thereofa worm 64 meshing with worms 65 on the shafts 62. At one end the shaft63 may be provided with an operating handle G6. IVith this kconstructionit will be apparent that as the handle is turned., the platform will be'raised or lowered. The pitch of the threads on the worms and wormwheels is such that when the handle is released, the thread will form anefficient lock, thereby effectively holding the platform in its adjustedposition. This makes it possible to readily move the platform as desiredfor fil-ling receptacles of different sizes whereby the fall ofmaterial. from the hopper reduced to a niininiuni.

Instead of utilizing vclamping arms 35 for coimecting the triggeractuatino' mechanism to vthe scales, I may provide a clamp G7, as shownin detail in Figures 16 and 17, carrying an arm 135 with an adjustable'eXt-ension This extension in turn carries a clamp 137cooperating with the rod' 138 having a pivotal connection with the endof the scale beam 1110. In this modification the opposite platform ofthe scales is adapted to hold the package, the lreiease mechanism beingoperated upon the upward movement of the rod 138 similar to theoperation taking place with the plat-form scales illustrated iny Figure9. f

The forms of my invention heretofore described have been particularlyadapted to the handling of bulk material, such as fiour, coffee, sugarand the like, adapted to readily flow in their natural condition. Byreason of the adjustments provided, the eX- tent of opening of theshutter sections could be varied, thereby causing a larger or smallerflow, depending upon'the material being handled and the size of thepackage or receptacle being filled.

In Figures 13, 1-1, 15 and 13 there is illustrated an apparatusparticularly adapted for the handling of fluids. These fluids may be ofthe character adapted to fiow freely under ordinary conditions, or maybeof the character adapted 'to be fed under pressure, as is the case withsome of the heavier oils and greases, or fed under either heat alone orheat and pressure, as in the case of lard. For such materials the hopperis entirely eliminated and the material is supplied by a pipe having amanually operable control valve 71 and an automatically operable eut-offmeans 72. It has been founddesirable to utilize the shutter sections foroperating the cut-off valve 72, and to permit such an operation theshutter valve sections may be each formed with a recessed end 73. InFigure 15 I have illustrated shutter sections operating exactly in themanner disclosed in Figure 2, but of slightly different constructionsimplifying and cheapening the manufacture thereof.

The recesses 73 are of such size that when able mesh placed across itsoutlet.

the shutter sections are in closedposition, as illustrated in Figure 15,there is sufiicient room for the passage of the feed pipe 70. The valve72 may be of the well known construction comprising an upper sealingmember and a lower wedge-shaped seating member having an upstandingbearing 74 thereon 'iermitting substantially universal movement of theseating member. These members are mounted to swing with a shaft 75 intooperative position, as illustrated in Figure 18, and into inoperativeposition within the chamber 7 G. These i'novements may be accomplishedby providing the shaft 75 with an arm 77 bifurcated at its outerl end tostraddle the pin 78 projecting upwardly from a rod 79 adjustably mountedin the post 30 secured on-the lower side of'one ofthe shutter sections.By reason of this construction, it will be apparent that as the shuttersections are separated,` the rod 79 will be moved to the right, asviewed in Figures 15 and 18, thereby turning the shaft 75 in a clockwisedirection and moving the cut-ofiI means 72 into inoperative position.This will permit a fluid flow through the pipe 72 until suchv time asvthe weight of the receptacle is sufficient to tip the scales andthereby operate the trigger release through one of the mechanismsalready described. This will instantly cause the springs controlling theshutter sections to move the same to closed position, thereby turningVthe shaft 7 5 in the opposite direction to move the cutoff 72 intooperative position. I have found that with certain fiuids there is atendency for drops to accumulate even after the cutoli means has beenmoved to operative position due to accumulations on the sides of thedischarge outlet. This may be effectively overeome with certainmaterials by providing a removable nozzle Sl having a restricted outletof the construction illustrated in Figure 18. In other cases I mayutilize a nozzle 81', as shown in Figures 19 and 20, having a piece ofscreen S of suit- In order to permit clearing of the discharge nozzleshould the same become clogged, I preferably provide a clean-out plug 82as shown in Figure 13 so located that upon its removal a cleaning rodmay be moved freely through the lower end of the pipe 70. It will beunderstood that if desired a suitable fluid, such as hot water or steam,may be used as a cleaning medium. The construction and operation of theshutter sections in the forms of my apparatus illustrated in Figures 10and 13, respectively, is the same with the exception that in Figure 10the shutter sections are not provided with recesses 73 and are not usedin conjuction with a supplemental cut-off 72 and its operatingconnecions as required for the handling of flui s.

The present application is a division in part otiny application, Serialtiled March E23, 1928. j

It will be apparent to those skilledinthe art that the constructionoithe lsupporting frame may bemodilied at will byvaiyiiig the number otSupporting standards, or otherwise, to thereby facilitate the use oitheiapjiaratus and removal oi filled packages therefrom. j

In Vcertain cases it may befdcsired to increase` this effectivenessofthe Arolling ball to secure a greater' impact. This may'easily beaccomplished Within the scope oi my invention by merely shortening thelength of the scalebeam 40', 40-`o'r 140, or moving the point of`attachment ot the rody 3S, 38 or 138 sloivto its pivotal mounting.

lith all ofthe iforii'isot` my invention illustrated herein there isyprovided a cut-oil means which is4 auton'iatically,releasednpon theaccumulation Vina re'ceptacleor package oi' a predetermined amountofiiiaterial.V fis soon" 'as the lillcd` 'package or 'receptacle hasbeen removed j' i l 'ointne scalesraiid a 'fresh receptacle placed inposition tl eoperator may quickly set the apparatus`` by simply drawingthe handle the controlling bell crank doivnivardlyto openthe 'shuttersections. Th'e'exteiit of opening'movement of the sections may bevvaried and controlled at will, and the sections may be locked in anydesired open position by the detent and trigger; This permits` uniformlcpiantities ot' the material to be packaged as rapidly as it ispossiblefor the operator-"to remove filled packages or 'receptacles and supplynew ones, allovving time only for the actual filling operationi lGtheradvantages arise trom the provision of'thesecond scale'beam,whereby the releasing mechanism for the triggermay be itself delicatelybalanced so as to move easily and effect the desired release of theshutter sections.

Further advantages arise from the provision of a positively acting orimpact means for effecting the trigger release.
